It's definitely going to have 2 screens and any idiot with half a brain stem could tell you the same. Whether it has two touch screens is not something anyone can really make a call on. It makes a little sense, but it would be nigh on impossible to make effective use of both screens.

I remember reading that it WILL have 2 screens, however what's seperating both screens will be very small so they are almost connected giving the option for 2 or 1 screen gameplay, so having both of them touch screen is not a stretch...

Two touchscreens and that is based on the rumour that they can act as one big screen which I reckon will be slide-able so that the camera on some DSi Enhance games can be used...unless Nintendo won't support that in those games.
